Geneva, 31 January 2011. CERN1 today announced that the LHC will run through to the end of 2012 with a short technical stop at the end of 2011. The beam energy for 2011 will be 3.5 TeV. This decision, taken by CERN management following the annual planning workshop held in Chamonix last week and a report delivered today by the laboratory’s machine advisory committee, gives the LHC’s experiments a good chance of finding new physics in the next two years, before the LHC goes into a long shutdown to prepare for higher energy running starting 2014.

Geneva, 17 December 2010. Delegates attending the 157th session of the CERN Council today congratulated the laboratory on the LHC’s successful first year of running, and looked forward to a bright future for basic science at CERN1. Top of the agenda was the opening of CERN to new members. Formal discussions can begin now with Cyprus, Israel, Serbia, Slovenia and Turkey for accession to Membership, while Brazil’s candidature for Associate Membership was also warmly received.
Geneva, 6 December 2010. The ASACUSA1 experiment at CERN2 has taken an important step forward in developing an innovative technique for studying antimatter. Using a novel particle trap, called a CUSP trap, the experiment has succeeded in producing significant numbers of antihydrogen atoms in flight. This result is published today in the journal Physical Review Letters.
Geneva, 26 November 2010. After less than three weeks of heavy-ion running, the three experiments studying lead ion collisions at the LHC have already brought new insight into matter as it would have existed in the very first instants of the Universe’s life. The ALICE experiment, which is optimised for the study of heavy ions, published two papers just a few days after the start of lead-ion running. Now, the first direct observation of a phenomenon known as jet quenching has been made by both the ATLAS and CMS collaborations.
Geneva, 17 November 2010. The ALPHA experiment at CERN1 has taken an important step forward in developing techniques to understand one of the Universe’s open questions: is there a difference between matter and antimatter? In a paper published in Nature today, the collaboration shows that it has successfully produced and trapped atoms of antihydrogen. This development opens the path to new ways of making detailed measurements of antihydrogen, which will in turn allow scientists to compare matter and antimatter.
